Speccaton of Letters Patent. Patented July 26:, 1921.

Application filed March 22, 1920.V Serial No. 367,902.

apparatus, and for the 'purpose of illustra-- tion the improvements are shown thus applied, but it will beA understood that the invention is not necessarily limited thereto, or to any specific form of press,.and the right is therefore reserved of applying the iniprovenients to any forni of press and to presses employed for any purpose and to which it is applicable.

rlhe object of the invention isto simplify and improve the construction of devices of this character and increase the eliiciency without increasing the expense orcomplicr.- tion of parts, andto this end the invention consists in certain novel features of construction as hereinafter' shown and described and specified in the claims.

ln the drawings illustrative of the invention in which corresponding parts are denoted by like designating characters;

Figure 1 is a longitudinal sectional elevation.

Fig. 2 is a transverse sectional elevation, on the line 2-2 of Fig. 1.

Fig. 3 is a sectional detail of the plunger and one of the traveling nuts and the toggle levers illustrating the construction and action.

Fig. 4-is a perspective view of the follower head, detached.

|llhe improved device may be applied with slight and unimportant modifications to nearly all the ordinary forms of baling presses, but for the purpose of illustration is shown applied to an ordinary form of cottonpress, in which 10 represents the base frame upon which the press box 11 is supported by a vertical intermediate frame 12, the latter carrying a screw shaft 13, centrally mounted for rotation by spaced bearings 14-15 beneath the press box and car rying a bevel gear 16 between the bearings, as shown.

The ends yof the screw protruding from beyond the bearings 1-15 are threaded in reverse order or right and left handed, as shown, and the ends are provided respectively with nuts 19-20, the latter having sockets 21-22- respectively in their lower ends in alinement with the screw shaft, and in their upper sides with spaced sockets 23-24, as shown.

Beneath the screw 13 upon the base frame 10 a track member 25 is carried, and mounted for-rotation, as by journals 26-27 in the sockets 21-22, are rollers 23-29 bearing upon the track, as shown.

tiovablein the press box 11 is a follower` head 30 having spaced sockets 31-32 near its ends and withV spaced studs 33-34 ein tending therefrom, and resting upon the carier head is a block v.35 having spaced apertures through which the studs extend and above whose upper surface they protrude, as shown.

A follower plate 36 rests upon the block 35 and is provided with recesses to receive the protruding ends of the studs, as shown, and by which means the follower plate is supported detachably in position relative to the follower head and its block.

Jeurnaled by their upper ends, as by pins 37-33, in the spaced socket 31-32 and likewise by their lower ends, as by pins 39-40,

in the sockets 23-24, are toggle leversy 41-42 arranged in pairs and spaced apart corresponding to the spaces between the sockets 31-32 and 23-24.

The ends of the toggle levers will preferably be concentric to Atheir pivot pins, and will engage the bottoms of their respective sockets, so that the strain and end thrust will be borne by the levers, and the pins thereby relieved from the strains, as hereafter more fully explained.

The drive shaft is represented at 43 and mounted as by bearings 44 upon the base frame 10 and carrying a bevel pinion 45 for engagement with the bevel gear 16, the bevel gear 45 being preferably the smaller to secure an increase of power between the shaft 43 and screw 13, as will be obvious.

Any suitable motive power may be applied to the shaft 43, and it may be rotated at any required or suitable speed.

rl`he press boX is of the usual shape and is shown formed with two receptacles for the material to be compressed mounted to swing upon a central clamp rod 46 and held in position by spaced clamp bolts 47 and clamp frame 4S in thc usual manner, so that one press boX may be supplied with the material to be compressed while the material is being compressed in the other, as will be obvious. l

By this arrangement of parts a very powerful pressure may be exerted upon the follower' plate and the strains so uniformly distributed that no-,danger exists of fracturing or straining the screw and other parts.'

It will be noted that the lateral thrust and strains are borne entirely by the nuts 19H20, thus relieving the screws entirely of lateral strains and leaving them free to perform their legitimate function of drawing the nuts and the toggle le inwardly and thus actua'te the follower head and plate.

l'V hen it is desired to compress bales to a greater `extent one or more additional follower plates may be inserted either abov or below the bale and the toggle levers again actuated, with the result of decreasing the size of the bale, to an extent equal to the vthickness of the additional follower Yplate press boX and having spaced guide studs extending therefrom, and av follower plate carried by said follower head and havingA nected to the nuts, of a follower' head mov4 able in the pressV box, a bearing block carried by said follower head, a follower plate carried by the bearing block and means Caried by the follower head for retaining the bearing block and follower plate in position on the follower head said toggle levers being' p ivoted by their respective ends in said nuts andfollower'heads. Y Y

Y ln a device of the class described a press box, a follower head mounted for movement in said press boX, and a bearing block carried by the follower head, the fol lower head and bearing block having interengaging elements whereby the bearing block is retained in position on the follower head. Y y

ln testimony that I claim the foregoing as my own, I have` hereto aflixed my signature in the presence of two witnesses.
